Yeah, I thought the chair looked familar... Vegeta shouldn't be upset... He went up four super saiyan levels later on. Pls notice that unless you've already watched Dragonball GT you probbaly don't know about the Super Saiyan 4. The Super Saiyan 4 is not in Dragonball Z. Sorry Z fans.

I love this picture, but i also think you should re-attempt and experiment a bit> Per your explanation, i would think Vegeta to be resting his head on that right arm of the throne using the same fingers to pinch the bridge of his nose with his eyes closed. Just a thought. I feel like you would get more feeling from it.
